# When a release is published on this repo (or manual dispatch):
#   1. Builds the Electron launcher from that tag (npm run pack:win).
#   2. Downloads any assets attached to the same release on this repo (patches, Wow exe, …).
#   3. Merges them (launcher files win on name collision) and creates/updates the matching
#      release on Fractured-Distro.
#
# Setup (GitHub → Settings → Secrets and variables → Actions):
#   DISTRO_SYNC_TOKEN — PAT with releases write on Fractured-Distro (see repo README).
#
# Change DISTRO_REPO or the job `if:` if your GitHub slugs differ.
